Traditional light-alloy fusion process is that light-alloy ingot is directly carried out to melting in an atmosphere, magnesium alloy melting in an atmosphere, one
As the melting under protective gas (mixed gas of SF6+N2) or the protective effect of solvent, and aluminium alloy is generally directly exposed to greatly
Melting is carried out in gas.Direct melting in an atmosphere, the factor for influencing atmospheric environment is sufficiently complex, as there is DIFFERENT WET in the different time
Degree and temperature etc., are difficult to find its changing rule, and the melt quality of light-alloy melting is influenced greatly by these factors, for one
The production of a little light-alloy spare and accessory parts of less demanding, the influence of above-mentioned factor will lead to product quality and fluctuation occur, cause
Rejection rate increases, needless to say the crucial light-alloy spare and accessory parts in the fields such as Aeronautics and Astronautics and military project, the consequence of generation more cause
Life.
It is influenced to overcome by various environment, some enterprises begin trying to block external environment pair with vacuum melting technology
The influence of Melting Quality, carries out the melting of high-quality light-alloy, which is proved the height for producing high-quality of energy small lot
Tough light-alloy spare and accessory parts, but generally use existing commercially available vaccum sensitive stove, can only single furnace carry out small lot melting, and pour
Note process is inconvenient, and efficiency is lower, can not be used on a large scale.
Summary of the invention:
The purpose of the present invention is be difficult to provide high-quality for the light-alloy melting technique being exposed to the atmosphere traditional at present
Light-alloy melt, although and traditional vacuum melting technique can provide the light-alloy melt of high-quality, efficiency is lower, it is difficult to big rule
The status that mould uses develops a kind of efficient, energy-efficient high-quality light-alloy melt smelting equipment, both makes full use of vacuum melting
Advantage, and overcome the inefficient of traditional vacuum furnace, provide equipment guarantee for the extensive utilization of high tough light-alloy spare and accessory parts.
In order to achieve the above objectives, mentality of designing of the invention is: developing a kind of collection high-quality melting and quantitative pouring is
The vacuum drying oven of one, this vacuum drying oven is heated using the energy-efficient novel superaudio induction heating technique of Present Attitude, to mention
The efficiency of high light-alloy melting, and reduce the energy consumption index of melting；It opens up on the bell and crucible cover of vacuum drying oven and individually may be used

(1) certain angle is arrived, inert gas is allowed to enter crucible (10) inside by certain flow, after being full of inert gas in vacuum drying oven,
External feeding lid (5) and interior feeding cover (6) are opened, is then successively closed toward crucible (10) internal light-alloy ingot that constant weight is added
Interior feeding cover (5) and external feeding lid (6) are closed, and is sealed, inert gas gate valve (1) is simultaneously closed off, then, opens vacuum valve
(19), vacuum drying oven inside is vacuumized by vacuum pump, after reaching required vacuum degree, superaudio induction heating line
(11) energization and logical cooling water are enclosed, crucible (10) is heated, after crucible (10) is heated, transfers heat to the light of its inside
Alloy pig makes the heating fusing of light-alloy ingot, and temperature thermocouple (4) measures crucible internal temperature, needed for temperature reaches
After setting technological temperature, vacuum drying oven enters keeping warm mode, after extraneous pouring condition meets, opens inert gas gate valve (1), presses
Certain flow is passed through inert gas toward crucible (10) is internal, after crucible (10) internal pressure is equal to external atmosphere pressure, opens defeated
Then the perfusion tube sealing flange (8) of liquid pipe (21) outer end increases inert gas gate valve (1) opening, by certain flow by earthenware
Light-alloy melt (20) in crucible (10), which pours, to be outpoured outside vacuum drying oven, is completed light-alloy melt quantitative casting process, is worked as casting complete
Afterwards, the perfusion tube sealing cover of perfusion tube (21) outer end is installed into return, realizes isolation inside perfusion tube and extraneous, subsequently into
Next melting circulation.
The present invention is directly exposed to the light-alloy smelting furnace and traditional vacuum smelting furnace phase of melting in atmosphere with existing tradition
Than there is following effect:
1, relative to the light-alloy smelting furnace for being directly exposed to melting in atmosphere, external environment can be blocked to the shadow of fusion process
It rings, conducive to the control of light-alloy smelting parameter, can ensure the stability and reproducibility of various smelting technology parameters, it is light using ensureing
The quality of alloy melt, light conjunction needed for being especially suitble to the production of the fields such as military and aerospace high-quality light-alloy spare and accessory parts
The preparation of golden melt；
2, using the newest superaudio induction heating technique of existing market, it is more traditional in frequency induction heating it is more energy saving and high
Effect；
3, relative to traditional vacuum induction melting furnace, increase convenient for charging device and inert gas piping, be conducive to quickly to
Charging in crucible equally on the basis of ensureing that furnace inner environment is stablized, improves smelting efficiency without the environment destroyed in furnace；
4, relative to conventional vacuum induction furnace, the design of the structures such as perfusion tube is increased, during melting, perfusion tube and infusion
Seal of tube lid etc. is in sealing state, and at the end of melting, toward crucible inside be passed through inert gas progress melting protection, and beat
Perfusion tube sealing cover is opened, then increases the flow of inert gas, it, can be quickly by melting in crucible under the action of inert gas pressure
Good light-alloy melt conveying goes out vacuum drying oven, and enters in the mold of outside, completes the production of light-alloy spare and accessory parts, the invention compared with
Traditional vacuum furnace, more automatic casting functions, substantially increases the efficiency of vacuum melting.
